To enable more efficient combustion control in residential heating appliances, Cubic leverages its extensive sensor R&D expertise and strong in-house manufacturing capabilities to deliver an intelligent combustion control system, from sensors, controllers to actuators, driving system-level innovation and performance improvements.
Cubic provides self-developed and in-house-manufactured key boiler components, including heat exchangers, gas valves, gas blowers, and controllers, serving as the foundation of intelligent combustion control systems, which are specifically designed for long-term, stable, and high-efficiency heating applications.
Leveraging advanced ultrasonic, Zirconia-based limiting current, NDIR, TDLAS and electrochemical sensing technologies, Cubic provides a comprehensive portfolio of gas sensing solutions for heating applications. Cubic innovative ultrasonic air/gas flow combo sensor enables precise air-gas ratio control for optimized combustion performance. High-precision Zirconia O2 sensors, NDIR CO2 sensors and electrochemical CO sensors deliver effective flue gas monitoring, helping optimize combustion efficiency, reduce energy consumption and lower emissions. Meanwhile, dedicated TDLAS CH4 sensors and electrochemical CO sensors provide highly reliable gas leak detection, enhancing operational safety and protecting both equipment and occupants.
Cubic's residential combustion control system portfolio includes the C110S, C220S, and C320S series, meeting different boiler platform and application requirements.
The system is adaptable to multiple gas sources, including natural gas, LPG, and hydrogen-blended natural gas. By dynamically regulating the air-gas supply ratio according to operating conditions, they support stable combustion, precise temperature control, and reduced emissions.
The capability can not only significantly improve the thermal efficiency of the system to reach 108% based on Lower Heating Value (LHV), but also effectively reduce NOx and CO emissions, helping the whole machine to meet the European Class 6 emission standards.
